Exchange 2010 SP2 Error after upgrading to Rollup 5

This post is also available in: Polish

 

Unfortunately last update released by Microsoft for Exchange 2010 SP2 (Rollup 5) causes many issues with Exchange DAG.

After installation of Rollup 5 for Exchange 2010 SP2 you will receive EventID 4999 in Event Log and also you won’t be able to run Get-DatabaseAvailabilityGroup -Status and the MSExchangeADTopology service started acting strangely.

Like we said first test this Rollup 5 in your test environments.

In Event Log you will find errors 4999 like below about watson:

Watson report about to be sent for process id: 792, with parameters: E12, c-RTL-ADM64, 14.02..0318.004 RemotePowershell, M Exchange Management 
M.E.C.R dagTaskHelper.GetServersInDeferredRecovery, System.TypeLoadException, 253d, 14.02.0328.005

 

and when you run below command:

Get-DatabaseAvailabilityGroup -Identity DAG01  -Status

 

you will receive error like below:

 

After uninstallation of Rollup 5 all errors goes away.

So for now we recommend do not install this rollup in production environment.

  1. Had the same when I tested it two days ago.
    Reported the issue to MS so they are ware but RU5 hasn’t been retired from the download site (yet).

    I haven’t seen an official statement from Microsoft.

    We it means we us authors of this blog.
    We always recommend to install new Rollups in Lab/Test environment first.
    Even Exchange Team Blog didn’t write anything about released this Rollup 5 :(

    Thanks for the clarification.
    Maybe you should update your post at http://social.technet.microsoft.com/Forums/en-US/exchange2010/thread/df0e3031-6efd-4611-a2ee-4f40e523ac3c#21225938-b6e6-44af-b3c0-b949a93fc68e

    .where you write that “it’s not recommended to install now” and say something like that you don’t recommend it.
